FIELD: machine building.
SUBSTANCE: wiper planetary gear drive comprises lever with wiper brush. Wherein drive mechanism comprises motor, housing accommodating input shaft rigidly coupled with motor shaft, coaxial intermediate and output shafts. Wherein lever with wiper brush is rigidly secured at output shaft. An elliptical gear wheel is fixed on the housing, another elliptical gear wheel is installed on the output shaft. A spur gear wheel is installed on the input shaft and is connected to the carrier by a gear transmission. Carrier is installed on intermediate shaft and is connected through rotary kinematic pair to satellite shaft consisting of elliptical gear wheel and elliptical pinion gear, wherein the satellite elliptical gear wheel is connected to the elliptical gear wheel, and elliptical pinion gear is in gearing with elliptical gear wheel. Counterweight is installed on the carrier opposite to the satellite shaft.
EFFECT: decreased overall dimensions in radial and axial directions.
